First you have to find a common denominator between the two fractions.
Since 16 is a multiple of 2, and 2 x 8= 16, multiply 1/2 by 8/8:
1/2 x 8/8= 8/16
Then you can add that to 11/16:
11/16+ 8/16= 19/16
5/8 + 1/16 = 10/16 + 1/16 = 11/16
1/5+1/11 = 11/55+5/55 = 16/55
11/16 and 5/8 is 1 5/16.
I don't know what visual model is, but 1/2 + 3/16 = 11/16 .
You don't as first part is 11/16 in its simplest form and second is 3/4 in its simplest form. Add 1/16 to the first part.
(5/12) + (11/12) = 16/12 = 4/3Or: 1 and 1/3
Here are the steps to solve this problem: 1. Convert 1/8 so that it has the same denominator as 11/16 (that is, multiply numerator and denominator by 2). 1/8 = 2/16 2. Add the numerators. 11/16 + 2/16 = 13/16 13/16 cannot be reduced. So, 11/16 + 1/8 = 13/16.
11/16 − 1 = -5/16
Basically, 3/3 equals 1. So 1 plus 1/16 is 1 and 1/16. Or 17/16.
1/2+1/4+1/8+1/16 give all the fractions the same denominator =8/16+4/16+2/16+1/16 add them up =12/16+3/16 =15/16 hope it helped (:
-1/16 + 5/16 = 4/16 = 1/4
1/2 = 8/16Now we have the same denominator for all our fractions we can add the numerators, so:7/16 + 7/16 + 8/16 = (7+7+8)/16 = 22/16We can simplify 22/16 to 11/8 = 1 3/8 (as a mixed number) = 1.375.
